A 45-year-old female with a long history of HLA-B27-positive ankylosing spondylitis and ulcerative colitis developed cyclic neutropenia. She was hospitalized for high fever during each of three consecutive episodes of absolute neutropenia. On the third hospitalization, granulocyte-colony-stimulating factor (G-CSF), 5 micrograms/kg/day, was given by subcutaneous injection and resulted in an increase of absolute neutrophil count from 0 to 2.2 x 10(9)/liter and an associated decrease of platelet count and hemoglobin as well as severe bone and joint pain predominantly in the middle and lower back and purulent diarrhea. The back pain necessitated discontinuation of the drug. Oral cyclosporine therapy was begun, and although the neutrophil count continued to oscillate, both the peaks and the nadirs were higher than previously, and symptoms of neutropenia subsided. We conclude that cyclosporine can be an effective treatment for cyclic neutropenia associated with autoimmunity since G-CSF may cause exacerbations of autoimmune disorders.

Low-dose, subcutaneous recombinant human granulocyte colony-stimulating factor (rHuG-CSF, Lenograstim) was administered to 40 cancer patients (17 men, 23 women) enrolled from two medical centers to verify its clinical effectiveness and safety. The patients' mean age was 50.3 +/- 14.9 years. In this study, there were 20 patients with non-Hodgkin's lymphoma, 10 with breast cancer and 10 with various other solid tumors. The patients first received a course of chemotherapy without rHuG-CSF (control cycle). All patients had at least one episode of neutropenia or leukopenia during the control cycle. rHuG-CSF (2 micrograms/kg/day) was given subcutaneously for 10 days during the study cycle starting on the fourth day of chemotherapy. The nadirs of absolute neutrophil counts (ANC) were 1.8 +/- 0.25 x 10(9)/L and 0.27 +/- 0.05 x 10(9)/L for the rHuG-CSF cycle and pre-rHuG-CSF control cycle, respectively. The number of days of ANC < 1 x 10(9)/L were 1.03 +/- 0.29 and 7.38 +/- 0.58 for rHuG-CSF and control cycles, respectively. The duration from nadir to recovery of ANC (> or = 2 x 10(9)/L) was 9.68 +/- 1.15 days in the rHuG-CSF cycle, vs 22.53 +/- 1.03 days in the control cycle (p < 0.0001). No patient withdrew from the study. Adverse events were mild, with 12.5% to 40% of patients developing myalgia, general malaise, back pain, anorexia or fever. These side-effects were tolerable in all cases. The biochemical abnormalities were subtle and negligible. rHuG-CSF 2 micrograms/kg/day given subcutaneously for 10 days beginning on the fourth day of chemotherapy is very effective (90%), safe and convenient.

Neutropenia is the dose-limiting toxicity of docetaxel in children. This Phase I trial was designed to determine the maximum tolerated dose, the dose-limiting toxicities, and the incidence and severity of other toxicities of docetaxel with filgrastim (G-CSF) support in children with refractory solid tumors. Docetaxel was administered as an i.v. infusion for 1 h every 21 days with a starting dose of 150 mg/m2 and an escalation to 185 mg/m2 and 235 mg/m2 in subsequent patient cohorts. G-CSF (5 microg/kg/day) was administered s.c., starting 48 h after docetaxel and continuing until the post-nadir neutrophil count reached 10,000/microl. Seventeen patients received 27 courses of docetaxel with G-CSF support. Generalized erythematous desquamating skin rash and myalgias were dose-limiting at 235 mg/m2. Localized and generalized rashes were seen at all of the three dose levels. Neutropenia (median nadir, 95/1microl) occurred at all of the dose levels but was brief in duration and not dose-limiting. Thrombocytopenia was minimal (median platelet count nadir, 139,000/microl), and the severity of neutropenia and thrombocytopenia did not seem to be related to the docetaxel dose. Other docetaxel-related toxicities included hemorrhage (associated with mucositis), sepsis, hypersensitivity reaction, transient elevation of liver enzymes, stomatitis, back pain, asthenia, and neuropathy. One minor response was observed in a patient with colon cancer. The maximum tolerated dose of docetaxel with G-CSF support in children is 185 mg/m2, which is 50% higher than the maximum tolerated dose of docetaxel alone in children and 85 % higher than the recommended adult dose.

CPT-11 + ADM therapy (CPT-11 40 mg/body x 2 days; Day 1 & 2, combined with ADM 20 to 60 mg/body x 1 day; Day 3) was given to four patients with relapsed and advanced non-Hodgkin's lymphoma, which was refractory to conventional chemotherapies. The symptoms of the patients at the beginning of CPT-11 + ADM therapy were fever (in two cases), dyspnea due to pleural effusion (in two), severe backache (in one), and jaundice with splenomegaly (in one). Their Karnofsky performance scales were 20 or 30%. Soon after the initiation of CPT-11 + ADM therapy, their clinical conditions improved dramatically, and they obtained a partial remission lasting 3.5 to 9 months. During the period of controlling lymphomas by this therapy, all patients had some time at home for 2 to 8 months. The adverse effects were vomiting, diarrhea, neutropenia and thrombocytopenia, but no lethal infection or hemorrhage was seen. We conclude that CPT-11 + ADM therapy is very useful for improvement of QOL and life prolongation of patients with non-Hodgkin's lymphoma, which is refractory to conventional chemotherapies and is even disseminated.

A 16-year-old girl was hospitalized because of anemia and thrombocytopenia in April 1998, and was diagnosed as having AML (FAB:M2). After failure of initial remission induction therapy, she was successfully treated with the MEC regimen as a second-line chemotherapy. On June 22, the first consolidation therapy was started. One week later, the patient developed a high fever with backache. Chest computed tomography (CT) on July 8 showed a 3cm mass lesion adjacent to the thoracic descending aorta in the left upper lobe. She was given fluconazole and antibiotics, and remained in remission. On July 24, the mass lesion changed to a cavitary lesion on chest CT, suggesting a fungal infection, probably aspergillosis. With recovery from neutropenia, the patient became asymptomatic, and fluconazole was changed to itraconazole. On July 27, she suffered sudden, massive hemoptysis and died. Autopsy revealed a localized adhesion between the cavitary lesion and the thoracic descending aorta, and the aortic wall was ruptured at this site. Microscopic examination revealed invasion of mucormycotic hyphae into the wall of the aorta with infiltration of inflammatory cells. The vasa vasorum were occluded by thrombi, in which mucormycotic hyphae were detected.

A 65-year-old man with a 3-month history of intractable back pain had previously received cytotoxic curative chemotherapy for non-Hodgkin's lymphoma. His postchemotherapy course had been complicated by febrile neutropenia, recurrent coagulase-negative staphylococcal bacteremia, and gastrostomy site infections. He was admitted with severe intractable lower back pain requiring high doses of intravenous narcotic analgesia. Magnetic resonance imaging of the spine was highly suggestive of disk infection. Fluoroscopically guided needle aspiration of the disk space was confirmatory, and both tissue and blood cultures were positive for coagulase-negative Staphylococcus species. Treatment included i.v. vancomycin and oral levofloxacin. The most common organism causing disk space infection is Staphylococcus aureus. but Staphylococcus epidermis should be considered in immunocompromised patients. Septic discitis is an important differential diagnosis of back pain and should be considered in any clinical situation associated with bacteremia.

Epidural abscess with and without associated meningitis after epidural corticosteroid injections for radicular back pain is a rarely reported complication. We report the occurrence of an epidural abscess and meningitis in a 70-year-old man after 2 epidural corticosteroid injections for treatment of acute radicular lumbar back pain. At the time of diagnosis, cerebrospinal fluid cultures grew Staphylococcus aureus, and the patient was treated with intravenous antibiotics. Possible predisposing factors for the development of an epidural abscess and meningitis in this patient include a 2-year history of neutropenia and an accidental dural puncture that occurred during performance of the first epidural injection. A literature search identified 11 reported cases of epidural abscess, 2 of epidural abscess and meningitis, and 1 of meningitis attributed to epidural corticosteroid injections. Eight of the 14 reported patients were immunocompromised, and 8 (67%) of the 12 in whom cultures of blood, cerebrospinal fluid, or epidural pus were performed had results positive for S. aureus. Antibiotic prophylaxis for S. aureus should be considered for immunocompromised patients undergoing epidural corticosteroid injections.

We evaluated the efficacy and toxicity of trastuzumab plus gemcitabine in patients with HER2-positive metastatic breast cancer (MBC). Sixty-four patients were enrolled, the majority of whom (95%) had been treated with an anthracycline and a taxane before study enrollment. Eligible women were treated with gemcitabine (1200 mg/m(2) weekly for 2 weeks with the third week off on a 21-day cycle) plus weekly doses of trastuzumab (4-mg/kg loading dose; 2 mg/kg thereafter) until disease progression. The median patient age was 55 years, and the median number of previously administered (including adjuvant) chemotherapy regimens was 3. Twenty-two patients were scored as 2+ for HER2 expression by immunohistochemistry; 39 patients scored 3+. Three patients were assessed as HER2-negative on central pathology review and were ineligible for evaluation. Fifty-nine of the 61 patients remained evaluable for response. The objective response rates were 38% in the intent-to-treat population (23 of 61) and 44% among the 39 patients with HER2 3+ expression. The median response duration was 5.8 months, median overall survival was 14.7 months, and median time to disease progression was 5.8 months. Trastuzumab plus gemcitabine was well tolerated. No cases of clinical congestive heart failure occurred. Grade 3/4 toxicities included asthenia in 4 patients, fever in 4, neutropenia in 18, dyspnea in 6, abdominal or back pain in 3, and edema and nausea in 1 patient each. The combination of trastuzumab plus gemcitabine appears to be well tolerated and effective for patients with HER2-positive MBC previously treated with chemotherapy.

Intravenous immunoglobulin (IVIg) is administered for various indications and generally considered a safe therapy. Most of the adverse effects (AEs) associated with IVIg administration are mild and transient. The immediate AEs include headache, flushing, malaise, chest tightness, fever, chills, myalgia, fatigue, dyspnea, back pain, nausea, vomiting, diarrhea, blood pressure changes, tachycardia, and anaphylactic reactions, especially in IgA-deficient patients. Late AEs are rare and include acute renal failure, thromboembolic events, aseptic meningitis, neutropenia, and autoimmune hemolytic anemia, skin reactions, and rare events of arthritis. Pseudohyponatremia following IVIg is important to be recognized. Renal failure, usually oliguric and transient, occurs mostly on using sucrose-containing products owing to osmotic injury. Among high-risk patients who have a previous renal disease, dehydration, diabetes mellitus, advanced age, hypertension, hyperviscosity, or are treated by other nephrotoxic medications, administration of a non-sucrose-containing IVIg product after accomplishing hydration, in a low concentration and a slow infusion rate while supervising urine output and kidney function, is recommended. Thromboembolic complications occur because of hyperviscosity especially in patients having risk factors including advanced age, previous thromboembolic diseases, being bedridden, diabetes mellitus, hypertension, dyslipidemia, or those receiving high-dose IVIg in a rapid infusion rate. Immediate AEs can be treated by the slowing or temporary discontinuation of the infusion and symptomatic therapy with analgesics, nonsteroidal anti-inflammatory drugs, antihistamines, and glucocorticoids in more severe reactions. Slow infusion rate of low concentration of IVIg products and hydration, especially in high-risk patients, may prevent renal failure, thromboembolic events, and aseptic meningitis.

Cabazitaxel, a novel taxane, was approved in June 2010 by the U.S. Food and Drug Administration for treatment of metastatic castrate-resistant prostate cancer (mCRPC) in men previously treated with docetaxel. In TROPIC (N = 755), an open-label, randomized, phase III trial, cabazitaxel (plus prednisone) was associated with improvement in median overall survival compared with mitoxantrone plus prednisone (15.1 versus 12.7 months, p < 0.0001) in patients with mCRPC who had progressed following docetaxel-based regimens. That corresponds to a 30% relative reduction in risk of death compared with the mitoxantrone regimen. In addition, significant benefit existed in median progression-free survival with cabazitaxel versus the mitoxantrone regimen (2.8 versus 1.4 months, p < 0.0001). Most common adverse events (AEs) associated with cabazitaxel were hematologic; the rates (all grade) of neutropenia, leukopenia, and anemia were greater than 90%. Diarrhea, fatigue, asthenia, and back pain were the most common grade 3 or higher nonhematologic AEs. Because expected AEs from cabazitaxel therapy can delay or even interrupt treatment, oncology nurses need to be aware of those risks and their management. This article reviews the vital role of nurses in identifying patients at high risk for AEs associated with cabazitaxel therapy and reviews strategies for prevention and management of symptoms.
